- Application filed December 28, 1925. Se1'ia1 No. 78,021..

This invention relates tonew. and useful improvements in surfac ng orplaning machines and has particular reference to such machines adaptedprimarily for use in the,

' inner face of each of-the ends 11 a'bearing planing'or surfacing ofroads. e p An important object of thepresent lnvention is the provisionof'such a machinefor use infremoving thebumps or irregularities on thesurfaceof the road. -Another object of the invention is to provide sucha machine 'havingarotrry cutting elementwhereby the bumps orirregularities V in the road will be cut away as themachine is propelledor drawn "thereover;

Another object of the invention 15 toyprovide such a machine which whilesimple in i construction, will nevertheless be strong,

sturdy and durable and eflicient in operation.

' p In the, drawings forming a part of this applicationand wherein li-ke'characters of j reference have been employed to designate 3corresponding parts throughout the several Figure '1 is a side elevationofa road I planing machine constructed in accordance with the presentinvention.

Figure 2 is a top plan view thereof with the engine platform and engin'eremoved.

, shown one embodiment of the present invention, it will be seen thatthere is provided a. substantially rectangular frame A, compris Figure 3is'a perspectiveview of one'of the guiding elements.

Reference now being had more particularly tothe accompanying drawingswherein for! the purpose of illustration has been ing the side membersand the ends 11, said side members being provided adjacent each endthereof with the oppositely disposed longitudinal slots 13. The frame Ais supported by the four'guide members 513, each raving therear verticalarm..14 and. the

' curved front arm connected at its lower end'with the lower end of thevertical arm 14., This arm is curved in the mannersho'wn inorder tofacilitate themovements of the guide members over theirregularities inthe road; Two of these guide members B are positioned within the frame Aat each end thereof, one adjacent each of the sides 10.

' The rear vertical arms'ltof said members are secured within thesmallsupporting bars 16'slidab1y mounted int-hefslots 13., while thearms 15 pass through; and are secured] i J 1.63 i 1,
